NOTE: The 2 x 64-GB SSDs installed in the PTX1000 support the
vmhost snapshot
currently running and active file system partitions, and
snapshot recovery
snapshot content stored in the backup disk. In addition, the 64-GB SSDs
support enhanced hardware resiliency through storage partitioning and
redundancy.
Earlier versions of the PTX1000 have 2 x 32-GB M.2 SATA SSDs. PTX1000
routers with 32-GB SSDs do not support the

Forwarding operations are performed by the Packet Forwarding Engines, which include
ASICs designed by Juniper Networks. The custom ExpressPlus ASICs enable the
PTX1000 to provide up to 2.88 terabits per second (Tbps) of forwarding capacity. The
ExpressPlus ASICs are connected to Hybrid Memory Cubes (HMCs). These
high-efficiency memory modules provide packet buffering, virtual output queue (VOQ)
memory, and improved logical system scale.

Benefits of the PTX1000 Router

Increased scalability—The PTX1000 scales to 3 Tbps in a single chassis, supporting
up to 288 10-Gigabit Ethernet interfaces, 72 40-Gigabit Ethernet interfaces, and
24 100-Gigabit Ethernet interfaces, giving service providers the performance and
scalability needed as networks grow. The purpose-built ASICs in the PTX1000 provide
enhanced packet processing for both full IP functionality and MPLS transport,
accommodating scale as traffic continues to increase and optimizing IP/MPLS transit
functionality.
Space efficiency—Providing high capacity in a compact 2U form-factor, the PTX1000
meets installation needs for peering Internet exchange points, peering collocations,
central offices, and regional networks, especially in emerging markets.
